By default, the Windows 10 operating system will automatically check for updates. When an update becomes available, Windows 10 will download the update to your computer, and install it. Updates to Windows 10 often include security fixes and new features. As such, it is important to update Windows 10 when new updates become available.

You can manually update Windows 10 if you can’t or don’t want to wait for the automatic download and installation. Windows may need to restart in order to complete the installation process. Windows 10 allows you to configure your active use hours, and to set a custom restart time if the update requires a restart. The option to defer feature updates is also available.
